Ethylamine.hydrobromide

Analogously, 2-(3,4-dihydroxyphenyl)ethylamine hydrobromide (dopamine) with 4-methoxybut-3-en-2-one (warm acetic acid) forms pyridinium salt 238 (yield 31 %) and quinolinium salt 239 (yield 40%) (64AG534 65AG224 80MI2). In aqueous solution at 20°C, only 239 is obtained (yield 13%). 

Base-treatment of the compound proposed to be l-(2-bromoethyl)-2-thiourea (m.p. 173.6-174.2°), formed by the reaction of 2-bromo-ethylamine hydrobromide with potassium thiocyanate, was reported to yield 2-amino-2-thiazoline 116 however, Klayman119 has shown that the product of the thiocyanate reaction is actually 2-amino-2-thiazoline hydrobromide (m.p. 176-177°). 3-(2,3-Dibromopropyl)-2-thioureas...

A mixture of N-benzyl-2-(2-methoxyphenoxy)ethylamine, methyl ethyl ketone, and 5-bromoacetyl-2-methylbenzenesulfonamide was refluxed with stirring. After cooling the reaction mixture, ethyl ketone was distilled off under reduced pressure and the residue formed was dissolved in benzene. Then, ether was added to the solution and after removing the hydrobromide of N-benzyl-2-(2-methoxyphenoxy)ethylamine precipitated, the solvent was distilled off under reduced pressure to provide a viscous oily product. 

In the case of catecholamines, the functional groups of particular interest include the nitrogen atom, the C-2 oxygen atom, the aromatic ring and the aromatic oxygen substituents (see Figures 2 and 7). For compounds I-VIII, the interatomic distances are tabulated in Table VI. These may readily be compared to the corresponding values from x-ray studies of three representative conformationally mobile phenyl-ethylamines, norepinephrine hydrochloride (IX), amphetamine sulfate (X) and mescaline hydrobromide (XI).
